METAL KNOCK-DOWN DOOR BUCK CONSTRUCTION WITH WOODEN TRIM Filed April 29, 1966 2 Sheets-Sheet 2 A TTOP/YEYJ United States Patent 3,364,623 METAL KNOCK-DOWN DOOR BUCK CONSTRUC- TZON WITH WOGDEN TRIM Samuel Skier, 63153 Alder-ton St, Rego Park, N.Y. 11374 Filed Apr. 29, 1966, Ser. No. 546,240 6 Claims. (Cl. 49-504) This invention relates to door frames, bucks, and the like and more particularly is directed to preformed knockdown door frames or bucks as used in fire resistant portal constructions.

Among the objects of the invention is to generally improve door buck constructions of the character described which shall comprise preformed basic parts of metal and auxiliary decorative molding strips of wood, which basic parts and strips shall be shipped for installation in a knocked down condition requiring a minimum of shipping space and be adaptable for use in hanging the door in any of the four desired positions, which door buck shall permit installation on the framed doorway after the plaster or plaster board is in place and finished, which molding strips shall interengage the basic parts in a novel fashion and render a simulated mitered joint at the top corners of the portal, which preformed features and ease of installation shall reduce labor costs on-the-job to a minimum, which shall be rugged in construction and practical to a high degree in use.

Other objects of the invention will in part be ob vious and in part hereinafter pointed out.

The invention accordingly consists of features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter disclosed, the scope of the application of which will be indicated in the claims following.

In the accompanying drawing in which an illustrative embodiment of the invention is shown:

FIG. 1 is a perspective view of a portion of a wall having a door buck embodying the invention installed in a doorway therein.

FIG. 2 is an enlarged sectional view taken on line 2-2 in FIG. 1 showing the metal jambs fitted over the plaster finish on both sides of the wall and secured to the vertical studs of the doorway by metal piercing nails which simultaneously retain the wooden molding strips in position.

FIG. 3 is an enlarged sectional view taken on line 3-3 in FIG. 1 showing details of the head piece fitted over the plaster finish on both sides of the wall and secured to the horizontal lintel of the doorway.

FIG. 4 is an enlarged vertical section taken on line 44 in FIG. 2 showing details of the interfitting connection between the head piece and jamb.

FIG. 5 is an enlarged front fragmentary elevational view of the right corner of the door buck installation shown in FIG. 1, and

FIG. 6 is an exploded fragmentary view in perspective of the head piece, jambs and wooden molding strips embodying the invention shown installed in FIG. 1.

Referring in detail to the drawings, 10 denotes a knock-down door buck or frame constructed to embody the invention seen to include a head piece 11 for extending horizontally across the top of the doorway and interconnecting at opposite ends thereof with vertically extending jambs 12.

Head piece 11, as seen in FIGS. 1, 3 and 6, is formed of sheet metal as a channel-shaped member having opposite side walls 1112 each formed with an inwardly bent longitudinally extending panel 11a forming a top finished ledge for the installed buck 10 from which a downwardly extending flange 11f extends for the purpose hereinafter more fully described. The bottom of head piece 11 3,364,623 Patented Jan. 23, 1968 is formed with a centrally extending depressed portion, U-shaped in cross section, forming a horizontal door stop portion 110, the latter being centrally oifset to provide a horizontal door framing portion 11d. In order to serve the intended purpose, head piece 11 has the bottom thereof cut back from, that is shorter than the overall length of panels 11a with side walls 11b having opposite tapered end edges 11e extending from the ends of panels 11a to the ends of the head piece bottom. As is clear from FIG. 4, door stop portion 11c is cut back further and terminates a spaced distance from each end of the bottom. Suitable components of an interconnection with the open ends of the jambs 12 are provided as a transverse angle piece 13 spot welded to the interior surface of the head piece bottom to extend along each cut back end thereof. Angle pieces 13 each have a downwardly bent portion 13a for engaging the upper end of each jamb 12.

In order to secure opposite ends of head piece 11 to the doorway lintel L as shown in FIGS. 3, 4 and 5, flanges 11 which are spaced by panel 11a to extend behind side walls 11b for abutting the finished wall surface of plaster or plasterboard P, have end portions extending beyond tapered end edges 11e of side walls 11b. An opening 11g may be provided in the extending portion of 11f to receive a suitable nail 15 or other fastenmg means.

Iambs 12, which are mirror images of each other, are likewise formed of sheet metal as channel-shaped members having opposite side walls 12b extending at right angles to the jamb portion thereof, the latter having door stop portions 120, U-shaped in cross section, projecting therefrom and positioned to provide vertical door framing portions 12d which align with horizontal door framing portions 11d of head piece 11 when in assembly as shown in FIGS. 1 and 3. The edges of side walls 12b have outwardly bent narrow flanges 12a. The opposite ends of jambs 12 may be squared off, that is, have edges extending at right angles with respect to the longitudinal axis of the jambs for standing flat on flooring F and also for engaging under transverse angie pieces 13, as is clear from FIGS. 4 and 5, permitting each jarnb 12 to be assembled with head piece 11 in any of four selected positions.

A pair of wooden molding strips 14 is provided for each jamb 12. The rear side of each strip 14 is formed with a longitudinal groove 14a for engagement by flange 12a of the jamb side wall 12b. As seen in FIG. 2 each molding strip 14 may taper in cross section from a relatively thick border portion 14b to a relatively thin edge 140, the rear surface portion 14d of strip 14 between edge 14c and groove 14a being recessed from that of border portion 14b to accommodate the thickness of jamb side wall 12b. Metal piercing finishing nails 16 are driven through molding strips 14 and jamb side walls 1212 into door framing studs S simultaneously securing jambs 12 and strips 14 to the doorway.

One of jambs 12 may be provided with conventional hinge plates 17, which may be suitably pre-attached to door framing portion 12d in any well understood manner. The other of the jambs 12 may have a conventional opening (not shown) cut out for a bolt socket plate.

The utility of the invention willznow be apparent. A doorway is framed in a wall W with vertical studs S and horizontal lintel L in the well understood manner. Wall W may then be finished on both sides with plaster or plasterboard P, or any other sheet surfacing material, such as real or simulated wood paneling, extending substantially to the edge of the framed doorway.

Door buck 10, delivered to the job in knock-down condition constructed as hereinbefore described and sized to fit the dimensions of the doorway and finished wall thickness, is simultaneously installed and assembled by first holding head piece 11 in position up against the lintel L. The proper position of head piece 11 may be determined in any suitable manner, as for example, by disposing each jamb 12 at an angle to the vertical, bringing the upper square end He thereof into aligned contact between one end of door stop portion 110 and the downwardly bent portion 13a of transverse angle piece 13, and then bringing each jamb 12. up vertically against studs S. Head piece 11 is then fastened to lintel L by nails 15 inserted through openings 11g. Each jamb 12 may then be removed for assembly with molding strips 14, the latter being positioned on jamb opposite side walls 121; with narrow flanges 12a seated in longitudinal grooves 140 and with an upper end portion of strips 14 extending beyond the upper ends of iambs 12, as will be clear from FTGS. 4, and 6. lambs 12 are now mounted in place in the aforementioned manner with the upper end portions of strips 14 extending to underlie head piece side walls 11b, to overlie flanges 11 and to abut panels 11a thereby effecting a simulated mitered corner with opposite tapered end edges 11e. lambs 12, carrying molding strip 1d, may then be plumbed and fastened in position by nails 16.

The improved metal knock-down door buck with wooden trim strips herein disclosed is seen to achieve the several objects of the invention and to be well adapted to meet conditions of practical use. As various possible embodiments might be made in the above invention, and as various changes might be made in the disclosed construction, it is to be understood that all matters herein set forth or shown in the accompanying drawing are to be interpreted as illustrative and not in a limiting sense.
